SR-91 Westbound Lane Addition Project (I-5 to SR-57)

This project was completed in 2016.

The California Department of Transportation (Caltrans) and the Orange County
Transportation Authority (OCTA) added a new four-mile westbound lane to
SR-91 from approximately I-5 to SR-57 – delivering a better drive through
a key stretch between Anaheim and Fullerton. The new westbound lane
increased carrying capacity, improved driving operations and relieved traffic
congestion along this vital commuter and commerical corridor.
